SPIsolator Digital Isolators: We've Got Your SPI Bus Covered!

Supporting up to 40 MHz SPI clock speeds, the new digital isolators are more than six times faster, more than 80 percent smaller, and they cost as much as 85 percent less than competing optocoupler- or digital isolator-based solutions.

The ADuM3150 supports a delayed clock output on the part's master side that can be used with an additional general-purpose port on the master to support up to 40 MHz clock speeds.

The ADuM3150 is prereleased with evaluation boards now available.

The ADuM3151, ADuM3152, and ADuM3153 provide four high speed channels and three additional independent, low data rate channels in different configurations.

The ADuM3151, ADuM3152, and ADuM3153 are prereleased with evaluation boards now available.

The ADuM3154 digital isolator provides a slave select multiplexing system that allows up to four slave devices to be serviced from one isolator.

The ADuM3154 is prereleased with evaluation boards now available.
